C8051F921-G-GM 詳細描述
Product Overview
The C8051F921-G-GM from Silicon Labs is an 8-bit microcontroller built around an 8051 core and operating at 25 MHz. It provides 32 KB of FLASH program memory, 4.25 K x 8 bytes of RAM, and 16 I/O pins in a 24-QFN (4x4) surface-mount package. The device supports SMBus (2-Wire/I2C), SPI, and UART/USART interfaces, and includes a 15-channel, 10-bit analog-to-digital converter, PWM, temperature sensor, watchdog timer, power-on reset, and brown-out detect/reset functions. Its supply range is 0.9 V to 3.6 V, with an operating temperature range of -40°C to 85°C (TA).
Key Features
- 8051 8-bit CPU core with 25 MHz speed and an internal oscillator.
- 32 KB (32K x 8) FLASH program memory and 4.25K x 8 bytes of RAM.
- 16 I/O pins with SMBus (2-Wire/I2C), SPI, and UART/USART communication interfaces.
- Integrated 15-channel, 10-bit analog-to-digital converter for mixed-signal input measurements.
- On-chip peripherals include PWM, temperature sensing, watchdog timer, power-on reset, and brown-out detect/reset.
- Surface-mount 24-QFN (4x4) package with 24-WFQFN exposed pad case.
- 0.9 V to 3.6 V supply range and -40°C to 85°C (TA) operating temperature range.
Applications
- Low-voltage embedded control nodes using the 0.9 V to 3.6 V supply range and 16 I/O pins.
- Mixed-signal sensor acquisition using the 15-channel 10-bit ADC and temperature sensor.
- Embedded device-to-device communication over UART/USART, SPI, or SMBus/I2C interfaces.
- Compact surface-mount control modules using the 24-QFN (4x4) package and integrated peripherals.
Design & Procurement Notes
Designers should verify that the 0.9 V to 3.6 V supply range matches the system power rail and that the 24-WFQFN exposed pad is handled in the PCB layout and assembly plan. The 32 KB FLASH program memory and 4.25K x 8 bytes of RAM define the code and data space available for firmware. The 15-channel 10-bit ADC, temperature sensor, PWM, and communication interfaces can support mixed-signal and control tasks, while the internal oscillator and brown-out detect/reset, POR, and watchdog timer provide basic system supervision. The -40°C to 85°C (TA) range and surface-mount package should be considered during enclosure, board, and assembly planning.
